Portobello Mushroom Burgers Recipe

Use a grill rack or secure onions with wooden toothpicks to keep them from separating during grilling.
TOTAL TIME: Prep: 15 min. + marinating Grill: 10 min. YIELD:4 servings


  • 1/4 cup plus 3 tablespoons olive oil, divided
  • 6 tablespoons balsamic vinegar, divided
  • 4 slices onion (1/4 inch thick)
  • 1 teaspoon minced garlic
  • 1/2 teaspoon dried basil
  • 4 portobello mushroom caps
  • 1 tablespoon honey
  • 4 onion rolls, split
  • 4 lettuce leaves
  • 4 slices tomato
  • 4 ounces fresh mozzarella cheese, cut into 1/4-inch slices


  • 1. In a resealable plastic bag, combine 1/4 cup oil and 2 tablespoons vinegar; add onion slices. Seal bag and turn to coat; marinate for 30 minutes. Meanwhile, in a small bowl, combine the garlic, basil and remaining oil. Brush over both sides of mushroom caps; set aside.
  • 2. In a small saucepan, bring honey and remaining vinegar to a boil; cook for 5 minutes or until thickened. Set aside.
  • 3. Drain and discard marinade from onions. Using long-handled tongs, moisten a paper towel with cooking oil and lightly coat the grill rack. Grill onions and mushrooms over medium heat or broil 4 in. from the heat for 10-12 minutes or until tender, turning frequently.
  • 4. Serve on rolls with lettuce, tomato and mozzarella. Drizzle with reserved balsamic-honey sauce. Yield: 4 servings.
